Be it known that we, ISAACv W. HART and OMER NORTON, of New Britain, in the `county of Hartford, and

State of Connecticut, have invented a' new and improved Carpet-Fastener; and we do hereby declare that thev 'following is a full, clear, and exact description thereof, reference being had to the accompanying drawings,

and to the letters of reference marked thereon.

Figure 1 shows a top viewof the -fastener as applied vto a carpet. Figure 2 shows a side view of the same. .Figure 3 shon's a side view of the hook part A of the'fastener, detached. Figure 4'shows a side view ofthe leaf B, detached. l Figure 5 shows a front view of the part A. A Figure rshows a top view of the part A.

lFigure 7 shows a. top view of the part B. y

Our invention consists in a carpet-fastener, formed of two pieces, A and B, in which A is formed of one pieee'of metal, east or struck up in dies to the'shape shown in figs. 3, 5, and 6 in 'the drawings, and B consists Yof a strip of sheet metal, ofthe forro shown in figs. 4 and 7, which is secured under the pie'ee A, and, after the carpet is hooked down, is folded over the edge, in the manner shown in figs. land 2, to secure it in place. The part A is made with two hooks, c c, of a curved form, for hooking on the carpet, and two spikes or tacks, d'd, which are driven into the Hoor to hold the fastener in its place. The tongue or lea'f B is provided with two notches e e in its edges, through which the spikes d d pass, so as to secure the leaf B firmly in-its place n'heu the part A is driven int-o the door. The part Aean be made of brass or iron or any metal suitable for casting or swaging, and the part B of any rolled or sheet metal that has suilcie-nt flexibility to withstand the necessary bending` to take up and put down the carpet.

The operation of our iuventienin as follows: f lhe part B is placed under the part A, and both secured to the Hoor by driving in the spikes CZ d, as shown in figs. 1 and 2. The leaf B is left bent upward, as shmvn in iig. 4. The carpet is then hooked over the points Ve c, and theleaf B bent down over its edge, hold-Ing it securely in its place.

By means of our invention a carpet can be taken up and replaced as often as desired, while thefastener remains permanently attaehedte theloor.

What we claim as our invention, anddesire to secure by Letters Patent, is The colnbination of the devices A and, B for the purpose 'of a carpet-fastener, substantially as herein specified. v
